8/3:Detroit Lions rookie running back Kerryon Johnson looked solid in pass protection this week in training camp. Rookie runners often struggle with pass protection early on, so this is a great sign for Johnson in the long term as well as the short term. He might struggle for consistent fantasy value in 2018 with LeGarrette Blount and third-down back Theo Riddick in the picture, but the future is bright for Johnson. Johnson has the most upside of the group, though, and he's worth taking a chance on in the middle rounds.--Keith Hernandez - RotoBallerSource: The Athletic - Chris Burke
